Nissan S15 Silvia SR20DET
Spec R Models
Twin Cam, 16 Valve, Turbo
Set 4 Uprated Spark Plugs
NGK V-Power Racing Plugs
Heat Range 8
These plugs are heat rating 8 which is 2 steps colder than the stock plug. This is good for modified engines and can help prevent detonation or pre-ignition caused when the spark plug tip gets hot- causing a 'hotspot'. Colder plugs transmit heat away from the plug tip faster to avoid this. For more mildly tuned engines we also stock NGK 7 rated plugs, as well as the stock 6 heat rated plugs.
Please Note- These Racing Plugs are NON Resistor
